[0023] Embodiment

[0024] As Figure 1As shown in the figure, the device mainly includes a detector 10, which is configured as a cuboid frame. The cuboid frame is integrally formed by welding rectangular square tubes, having relatively high strength. A frame 11 is also provided at the end of the detector 10. When the detector 10 is installed horizontally, the frame 11 can be arranged at both ends of the detector 10. When the detector 10 is installed vertically, the frame 11 can be arranged at the bottom end of the detector 10. Among them, the first detection module 20, the second detection module 30, the third detection module 40, and the fourth detection module 50 are respectively installed on the four side surfaces of the detector 10. A rotating shaft is provided between the frame 11 and the detector 10, enabling the detector 10 and the frame 11 to rotate relative to each other through the rotating shaft. In this way, it is convenient for the staff to operate the four detection modules.

[0025] It should be understood that the detector 10 can not only be configured as a cuboid frame, but also as a hexagonal prism frame, an octagonal prism frame, etc., which can be set according to the number of physical property detection items of the enameled wire.

[0026] As Figure 2 shown in the figure, the first detection module 20 includes a first detection window 201 for placing the enameled wire and a first reduction motor 23 arranged on one side of the first detection window 201. Both ends of the enameled wire can be fixed in the first detection window 201, and one end of the enameled wire is driven to twist by the first reduction motor 23, for detecting the torsional performance of the enameled wire.

[0027] Furthermore, a first clamp seat 21 and a second clamp seat 22 for fixing the ends of the enameled wire are provided inside the first detection window 201, and the first clamp seat 21 and the second clamp seat 22 are located on the same axis. The first clamp seat 21 is fixed to the inner side of the first detection window 201, and the second clamp seat 22 is rotatably installed on the inner side of the first detection window 201, and the second clamp seat 22 can be driven to rotate by the first reduction motor 23. Among them, both the first clamp seat 21 and the second clamp seat 22 can adopt shaft-shaped wire clamps. The wire clamp includes two clamp plates that can be closed. When in use, both ends of the enameled wire are clamped and fixed, so that one end held by the first clamp seat 21 remains fixed, while the end clamped by the second clamp seat 22 can rotate. The first reduction motor 23 drives the second clamp seat 22 to rotate through its output shaft to perform a torsional test on the enameled wire. When the first reduction motor 23 rotates, the number of rotation turns can be recorded, and combined with the length of the enameled wire, the torsional resistance performance of the enameled wire can be judged.

[0028] As Figure 3 shown in the figure, the second detection module 30 includes a second detection window 301 for placing the enameled wire and a second reduction motor 35 arranged on one side of the second detection window 301. One end of the enameled wire can be fixed in the second detection window 301, and the other end is driven by the second reduction motor 35 to rotate around the connection point of the enameled wire and the second detection window 301, for detecting the bending performance of the enameled wire.

[0029] Further, a third clamp seat 31 for fixing the end of the enameled wire is fixedly provided inside the second detection window 301. The output end of the second reduction motor 35 is fixedly provided with a turntable 34. The axis of the turntable 34 coincides with the axis of the third clamp seat 31. A fourth clamp seat 33 for fixing the other end of the enameled wire is provided at the edge of the turntable 34. The fourth clamp seat 33 is rotatably connected to the turntable 34. Both the third clamp seat 31 and the fourth clamp seat 33 can adopt shaft-shaped wire clamps. The wire clamp includes two clamp plates that can be closed. When in use, the two ends of the enameled wire are clamped and fixed. The third clamp seat 31 is fixed to the inside of the second detection window 301. When the second reduction motor 35 drives the turntable 34 to rotate, the fourth clamp seat 33 rotates eccentrically around the axis of the turntable 34, thereby driving the enameled wire to rotate around the connection point of the third clamp seat 31, and the bending performance at this point can be detected.

[0030] In a preferred embodiment, in order to adjust the bending radius of the enameled wire during the detection process of the enameled wire, a slip ring 32 is provided between the third clamp seat 31 and the fourth clamp seat 33. The enameled wire passes through the slip ring 32, and both ends are fixedly connected to the third clamp seat 31 and the fourth clamp seat 33 respectively. The slip ring 32 is on the same axis as the third clamp seat 31, and the distance between the slip ring 32 and the third clamp seat 31 is adjustable. The slip ring 32 is made of stainless steel, and the inner side is configured as an arc shape, which can reduce the wear on the enameled wire. The plate on the side of the second detection window 301 close to the second reduction motor 35 is set to be movable, and a protrusion is provided on the plate. Slide rails are provided on the inner walls of the other two sides of the second detection window 301, and the slip ring 32 is moved in the way of the slide rail, and the bending radius of the enameled wire is changed by changing the distance between the slip ring 32 and the third clamp seat 31.

[0031] As Figure 4 shown, the third detection module 40 includes a third detection window 401 and a tension sensor 43 and a tractor provided on both sides of the third detection window 401. The enameled wire can be pulled along the length direction by the tractor. The tension sensor 43 is used to detect the deformation of the enameled wire and detect the tensile performance of the enameled wire.

[0032] Further, a fifth clamp seat 41 and a sixth clamp seat 42 for fixing the ends of the enameled wire are provided inside the third detection window 401. The fifth clamp seat 41 is fixedly connected to the tension sensor 43, and the sixth clamp seat 42 is fixedly connected to the tractor. The fifth clamp seat 41, the sixth clamp seat 42, the tension sensor 43 and the tractor are on the same straight line. Both ends of the fifth clamp seat 41 and the sixth clamp seat 42 are connected by ropes, so that the fifth clamp seat 41 and the sixth clamp seat 42 can be pulled. When in use, the two ends of the enameled wire are respectively fixed on the fifth clamp seat 41 and the sixth clamp seat 42, and the sixth clamp seat 42 among them is pulled by the tractor to draw the enameled wire. The tension sensor 43 can detect the magnitude of the tension borne by the enameled wire, and detect the deformation amount or breaking force of the enameled wire under a certain tension through the pulling distance of the enameled wire by the tractor.

[0033] Further, the tractor includes a pulley block 44 and a winch 45. The winch 45 is fixedly arranged inside the third detection module 40. The pulley block 44 includes N fixed pulleys and N - 1 movable pulleys. A steel wire rope 441 is wound around the outer sides of the fixed pulleys and the movable pulleys, and the steel wire rope 441 is wound by the winch 45. The axes of the fixed pulleys and the movable pulleys are on the same straight line as the fifth clamp seat 41 and the sixth clamp seat 42. Among them, the fixed pulley group is fixed inside the detector 10, and the other side of the fixed pulley pulls the movable pulley group through the steel wire rope 441. Since the more the number of movable pulleys, the smaller the force required for the winch 45 to wind under the same force applied to the enameled wire, and the deformation of the enameled wire will increase exponentially according to the number of movable pulleys. Therefore, the detection accuracy of the deformation of the enameled wire can be improved.

[0034] It should be understood that transparent acrylic door panels that can be opened and closed can be arranged on the outer sides of the first detection window 201, the second detection window 301, and the third detection window 401, which can play a protective role and prevent the enameled wire from breaking and hurting people when testing the enameled wire.

[0035] As Figure 5 shown, the fourth detection module 50 includes a guide wheel group 51 and a laser diameter gauge 52. The guide wheel group 51 is arranged to drive the enameled wire to be conveyed. The laser diameter gauge 52 is arranged on the path of the enameled wire and is used to detect the surface defects of the enameled wire. Among them, the detection accuracy of the laser diameter gauge 52 reaches the micron level and can detect the surface defects of the enameled wire.

[0036] Since the detection accuracy of the laser diameter gauge 52 is relatively high, the dust on the laser window 521 affects the detection accuracy. At present, it is necessary to clean the laser window 521 at regular intervals to avoid affecting the measurement accuracy. Therefore, in order to keep the surface of the laser window 521 clean, at least one dust collector 53 is arranged on the front side of the laser diameter gauge 52 along the conveying path of the enameled wire. The dust collector 53 is provided with an "O"-shaped or "U"-shaped wire groove for the enameled wire to pass through. A plurality of air injection holes 531 are arranged around the circumference of the enameled wire in the wire groove. The fourth detection module 50 further includes an air pump 54. The air injection holes 531 are arranged to communicate with the output end of the air pump 54 and can direct the air flow to the surface of the enameled wire on the side away from the laser diameter gauge 52.

[0037] During operation, the air pump 54 can blow air on the surface of the enameled wire through the air injection holes 531 around the circumference of the enameled wire. The high-speed air flow passes through the surface of the enameled wire and can remove the dust on the surface of the enameled wire. In this way, the surface of the laser window 521 can be kept clean and the detection accuracy can be prevented from being affected.

[0038] Further, in order to mark the abnormal area detected by the laser diameter gauge 52, the fourth detection module 50 further includes a sprayer 55. The output end of the sprayer 55 is provided with a nozzle 56. The nozzle 56 is arranged on the conveying path of the enameled wire. The sprayer 55 is electrically connected to the laser diameter gauge 52.

[0039] In a specific embodiment, the sprayer 55 is configured to: be able to receive the abnormal signal detected by the laser diameter gauge 52, calculate the time T according to the conveying speed of the enameled wire and the distance between the laser diameter gauge 52 and the nozzle 56, and spray a mark on the surface of the enameled wire through the nozzle 56 after the interval time T. In this way, the sprayer 55 can be linked with the laser diameter gauge 52. When the laser diameter gauge 52 detects an abnormality at a certain place of the enameled wire, it sends a signal to the controller. The controller calculates the time for the abnormal place to reach the sprayer 55, and controls the nozzle 56 of the sprayer 55 to work after this time to mark the abnormal point, which is convenient for manual further confirmation and subsequent processing.

[0040] In a preferred embodiment, two sets of guide wheel groups 51 are provided. The laser diameter gauge 52, the dust collector 53, and the nozzle 56 are all arranged between the two sets of guide wheel groups 51. The guide wheel group 51 at least includes a guide wheel, a tensioning wheel, and a driving wheel. The driving wheel is connected to an external driving motor and is used to convey the enameled wire. The tensioning wheel plays a role in tensioning the conveying of the enameled wire to prevent the enameled wire from slipping or breaking during the transmission process. The driving wheel can also be connected to a length meter to measure the length of the conveyed enameled wire.

[0041] Combined with the above embodiments, by setting the detector 10 including multiple detection windows, each of which detects a certain performance of the enameled wire, such as bending performance, tensile performance, torsional performance, etc., the detector 10 has diversified detection capabilities, and the detector 10 is set as a prismatic structure, and the four side surfaces respectively have different detection functions, so that the overall structure of the detector 10 is relatively compact and occupies a relatively small area, which is especially suitable for testing the specific special performance of wire materials.
